Yup, fundamental phlosophical difference.

I don't carry nearly that much stuff EDC (and already resent the weight, bulk and nuisance factor of what I do carry). That being the case, I don't expect to be able to bivouac with my pocket contents (it's COLD out there right now), and darn sure will have a pack with me if expecting to either cross water or spend the night.

Overnighting with EDC seems like an interesting exercise, but I frankly don't have much interest in carrying that much gear all day, every day. Here in the 'burbs it doesn't seem to make much sense (well, to me) to have a whole lot of outdoor stuff in EDC- you're never unexpectedly that far from shelter on foot, and a credit card or cash will solve a LOT more problems than any equivalent weight in gear. In real wilderness, both are quite useless. Different areas, different scenarios.
